Space probes may be separated from their launchers by exploding bolts. (they bolt away from one another.) suppose a 4800-kg satellite uses this method to separate from the 1500-kg remains of its launcher, and that 5000 j of kinetic energy is supplied to the two parts. what are their subsequent velocities using the frame of reference in which they were at rest before separation?
